UNITED STATES ARTHUR EDWARD STROUD, 0]? LONG EATON, ENGLAND.

TWIST-LACE MACHINE.

Application filed August 21, 1920. Serial No. 405,083.

To all whom it may concern Be it known that I, ARTHUR EDWARD STROUD, asubject of the King of Great Britain, residing at I-Iycroft, WellingtonStreet, Long Eaton, in the county of Derbyshire, England, lacemanufacturer, have invented certain new and useful Improvements inTwist-Lace Machines, of which the following is a specification.

This invention relates to improvements in and applicable to twist lacemachines and has for its principal object to provide means forintroducing a weft thread between the warp threads and the bobbinthreads.

Further objects of this invention are improvements in the weft threadcarriers and improvements in the means for and in the method ofactuating same.

According to this invention the weft thread is introduced between thewarp and bobbin threads by means of a carrier pref-- erably extendingbeyond or up to the top of the bobbins when the same are in theircentral position. Such weft threads may be in the form of tubes throughwhich the threads pass or may be in the form ofneedles through which thethreads are threaded. There is preferably either one carrier at thefront or back of the warp threads for each length or width of fabric tobe made or one carrier at the front and back of the warp threads forevery width of fabric to be made and such carriers are actuated to movebackwards and forwards to lay their threads between the bobbin and warpthreads.

In the accompanying drawings Fig. 1 is a sectional elevation showingelements of a lace machine having reference to the present invention andweft thread carriers in position.

Fig. 2 is a diagrammatic view showing one method of actuating the weftthread carriers.

Fig. 3 is a digrammatic view showing another method of actuating same,and

Figure 4 is a diagrammatical plan view of the machine showing therelative disposition of the weft thread carriers to the carriages andcomb bars.

According to this invention as shown in Fig. 1, the bobbins l, bobbinthreads 2, and warp threads 3, passing through thread guides I, are allarranged and operated in the manner customary to twist lace machines.The weft threads 5 and 6 drawn off spools 7, preferably mounted on thefloor,

pass through weft thread carriers 8 and 9 up to the work.

The weft thread carriers may be in the form of tubes as shown or may bein the form of needles through which the weft carrier at either the backor the front of the warp threads.

For the purpose of description it is assumed that carrier 8 in Fig. l isshown as occupying a position to the front of warp threads 3 and carrier9 a of such threads.

Referring to Fig. 1, carrier 8 moves in one direction to lay the weftthreads 5 between warp threads 3 and bobbin threads 2. Bobbins 1 thenswing through warp threads 3 along combs 10 being actuated as in thelevers or go-through lace machines in the usual manner. The weft carrier9 then moves in a direction opposite to or the same as that in whichcarrier 8 previously position to the back moved and lays the weft thread6 between bobbin threads 2 and warp threads 3. Bobbins 1 once more swingback, weft thread 5 is laid between threads 2 and 3 and the cycle ofmovements is then completed. The bobbin threads 2 and warp threads 3 maybe continually twisting with one another to hold the weft threads inposition or such threads 2 and 3 may be held from twistm by holding thewarps from being shogge Also, when twisting, each warp preferably twistswith the same bobbin at each motion.

There may, however, be any convenient number of thread guides 4Lactuated by a jacquard or other suitable mechanism for varying thepattern of the fabric.

The carriers 8 and 9 are conveniently mounted on horizontal rods or thelike 11 and actuated in any convenient manner to move backwards andforwards in bearings 11 carried by the comb bars 12.- Also "thecarriages are removed from the combs opposite the positions where suchcarriers rest.

In the method of actuating the improved weft thread carriers 13 as shownin Fig. 2 such carriers are mounted on a horizontal bar or the like 14actuated through levers or the like 15 for increasing the travel of thecarriers 13 and such levers are actuated through a rod or lever 16 by ajacquard or other suitable mechanism, conveniently a spring maybeprovided asat 17 for'providing return motion of the carriers 13. Thesecarriers 13 are preferably hollow so as to permit the were threads topass therethrough as shown.

In the arrangement shown inFig; 3 the Weft thread carriers 18, pivotedat19, are actuated to rotate about such a pivot by a rod or the like 20connected tothe carriers at 21 and actuatedto move approximately horizontall'y backwards and forwardslby a jacquard or. other ,suitablemeans..A spring made whereby the eft thread carriers, are

idle at. certain periods.

Also, after the Wflft thread carrier has completed'its travel theWeftthread may be 'manner and such Work may be taken up at a constant orvariable rate.

I claim:
